Personally, I'd like to know what the most important (as measured, perhaps, as the most hits)
Ok, hang on--I'd actually say that you can get a pretty good idea of the most important signatures by sorting them in ascending order by hits. The higher the number of hits, the greater probability that each hit is an FP and the signature isn't helpful. Important caveats would be for the sigs that aren't alerting on "bad" traffic, but traffic that is usually good unless it's from a certain IP address (JAR files, exe files, etc.) or SCAN signatures. That nuance actually makes this kind of hard to do in a helpful way. It's for this reason that I want the manual submissions, not based on logs. ------------------------------------------------------------------------------ The modern datacenter depends on network connectivity to access resources and provide services.
